To alt 10. mm it may concern:

Be it known that we, LEWIS W. (JooswnLL and JAMES D. ABEL, citizens ofthe United States, residing at Taylorville, in the county of Christian,State of Illinois, have invented certain new and useful Improvements inMiners Caps and Lamps; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it apn 'tains to make and use thesame.

s invention relates to a miners cap and safety lamp and has for itsprimary object to eliminate all chances of explosion of fire damp as faras such explosions are due to the lamps used by minors.

While the oil. lamps now in use are theoretically safe, numbers ofexplosions have occurred through their use owing to rents or o enings inthe wire gauze cage surrounding t ie flame. I

In carr 1g out our invention we employ instead of the usual oil lamp, anelectric lamp and the novelty in our invention lies in the manner offixing this lamp and the batteries and switch therefor upon the cap.

In the accompanying drawings, Figure 1 is a front elevation of the cap,lf ig. 2 is a top plan view thereof, Fig. 3 is a vertical sectional.view taken in a plane from front to rear, and, Fig. 4 a bottom plan viewof the front portion of the cap.

in the drawings the cap proper is indicated The top or innercrown of thecap is padded as indicated at 7 and stitched to the outer crown or topis a pocket 8 in which are arranged dry batteries 9 of the storage type,these batteries being removable from the pocket by unb'utt'oninoa flap10 which forms closure for the pocket. Secured by suitable rivets, atits front portion, to the vizor of the cap and throughout its rearportion to the cap proper is a sheet metal casing 11 which may be of anysfiitable contour except that its lower or cap attached edges are curvedfrom front to rear to conform to the shape of the cap and render the capcomfortable to wean This "casing includes a vertical front wall 12 inwhich there is formed a threaded o ening 13 for the reception of sheetmetal frusto conical reflector 14 there being a socket l5 fitted in thesaid end of this reflector is the reception of an electric iamp A wasleads from one pole of the battery 9 to one contact of the lamp socketand leading from the other contact of the socket to a switch 18 is aWire 19, the other contact of the switch and the other pole of thebattery being connected electrically by means of a wire 20. This switch18 is fixed upon the under side of the vizor 6 and consequently may bereadily reached by the wearer of the cap to switchthe light on or off.The wires above mentioned are led through the casing and are inclosedthereby, the lamp, the reflector, and the switch being the only elementsexposed.

From the foregoing descri tion of our invention it will be seen that tis batteries, although light in weight are supported upon a ad and thatthe casing for t e wirin and for the attachment of the lamp andreflector is not only light in weight but is so curved or formed as tobe perfectly comfortable to the wearer ofthe cap. The casing, as shown,has a bottom portion conforming to the shape of the cap, which ends atthe upper crown of the cap, and is. then bent back, to form a base ofdouble thickness, upon which the battery is carried. The casing is thencontinued outward and downward, and finally secured to its vizor.

What is claimed, is

A miner s cap having a viz or, in combination with a pad secured to theinner crown of the cap, a sheet metal casing having a bottom portionconforming to the shape of the cap and ending at the u per crown of thecap and then being doub ed upon itself to form a base of doublethickness, the upper portion of the casing being bent outward anddownward, and secured to the vizor of the cap, the forward verticalportion of said casing having a threaded o ening, a frustoconicalreflector within sai opening, a lamp carried by said reflector, a fabricpocket having a flap secured to the outer crown of said capinclosingsaid base, a battery upon said base and within said pocket, anelectric switch secured to the under surface of said vizor, and electricconductors connecting said switch, lamp and batteries.

In testimony whereof, we affix our signa tures, in presence of twowitnesses.
